Process Data Output Words OUT[0] and OUT[1]
The terminal must be configured using the two
process data output words. The word OUT[0]
contains the command and the word OUT[1]
contains the parameters for this command.
The following configurations are possible:
–
Selecting a measuring range according to
the input signal
–
Selecting the mean-value generation (filte-
ring)
–
Changing the formats for the representation
of measured values
Current or voltage measurement is
selected by applying the measured si-
gnal to the current or voltage input
and then configuring the measuring
range.
